At least 10 Hanford workers were exposed to radioactive waste Tuesday at the nuclear cleanup site’s tank farm in southeast Washington.
Workers were removing a connection line that’s used to transfer radioactive waste between tanks when the contamination was detected. A test found radioactive waste on the workers’ skin and clothing. The contractor, Washington River Protection Solutions, says the contamination was low.
Tom Carpenter, who heads the worker advocacy group, Hanford Challenge, disputed that characterization.
